About mobile.dev

Maestro is an open-source end-to-end UI testing platform for mobile (iOS and Android) and web applications that enables teams to ship at 'agentic velocity.' It combines a human-readable YAML test format with powerful CLI and desktop apps, easy CI integration, and an AI toolkit (MaestroGPT) that can read device screen hierarchies and write comprehensive test plans autonomously. Built for reliability and speed, Maestro tests are deterministic, repeatable, and auditable. It supports cross-platform testing with a single framework, offers visual assertion capabilities, and provides cloud-based parallel execution for scaling. The platform is extensible with no vendor lock-in, battle-tested by thousands of teams, and designed to close the agentic loop for modern AI-driven development workflows.

Pros & Cons

Pros
  • Open-source and extensible with no vendor lock-in
  • Human-readable YAML tests that are deterministic and auditable
  • AI-powered test generation via MaestroGPT reduces authoring time
  • Supports iOS, Android, and web with a single unified framework
  • Fast setup: most users write their first test in under 5 minutes
  • Rich set of commands (tapOn, inputText, assertVisible, scrollUntilVisible, etc.)
  • Battle-tested by thousands of teams for reliability
  • CI integrations with notifications, dashboards, and pass-rate thresholds
Cons
  • Advanced cloud scaling and some AI features may require a paid plan (pricing on contact)
  • Steep learning curve for teams unfamiliar with YAML-based test frameworks

Best For

Mobile app developers: Author smoke tests for iOS and Android flows before merging code.QA engineers: Create cross-platform regression suites with visual assertions and stable selectors.Release managers: Gate releases with CI-integrated end-to-end tests and pass-rate thresholds.Product managers: Record and validate critical user journeys without writing code.Startups: Scale testing in the cloud to cover device/browser matrices early on.Enterprise teams: Run parallel test suites on Maestro Cloud for faster feedback cycles.Test automation engineers: Leverage MaestroGPT to generate commands and accelerate test authoring.Web app teams: Add end-to-end UI coverage for key web workflows alongside mobile.CI/CD owners: Integrate tests into pipelines to catch UI regressions before production.Design/UX teams: Use visual testing to detect unintended UI changes between builds.
